The LC-20AT is a workhorse for routine daily use. Two LC-20AT pumps may be used to achieve high-pressure gradient elution for the best gradient accuracy. Alternatively, one LC-20AT pump may be outfitted with a LPGE valve for low-pressure gradient elution.

Features LC-20AT

Enhanced Solvent Delivery Specifications
Flow-rate accuracy and precision in the micro-flow rate region have been improved with the addition of a new type of check valve and modifications to the solvent delivery control method. Non-polar organic solvents such as hexane can be delivered stably.

Improved Durability
New and improved plunger seal materials ensure robust, long-lasting performance. A sapphire plunger optimized according to its crystal structure and a precise plunger-holding mechanism help increase the service life of plunger seals and enable stable solvent delivery over long periods.

Space-saving Designs
An optional low pressure gradient valve (LC-20AD/20AT), CBM-20Alite system controller, and a seal wash pump (LC-20AD) can now be installed inside the solvent delivery unit, enabling 4-solvent gradient elution in a compact space. The LC-20AB high-pressure binary gradient pump delivers the performance of two LC-20AD pumps in one compact unit.
